I did most of it already. Just can't figure out what the y is http://imageshack.com/a/img824/1580/skdw.png

The y-intercept is -160/9 

The y-intercept separates celsius and fahrenheit. 
We know x = celsius and y = fahrenheit 
On the graph, you can look at the line, graphically, when x = 0, and y = 0. We know that water boils at 100 celsius and 212 Fahrenheit. You can plug in options into the y intercept to get various representations.
